You must complete this in Python and the programs should not take any command-line arguments. You also need to make sure your programs will compile and run in at least a Linux environment.    In this problem, you must implement a tokenizer for the Assembly instruction format: an operation type (e.g. SUBI) followed by a comma-separated list of parameters (e.g. R0, R1, 6). If a line has an invalid syntax, it should be skipped in the output. You do not need to check whether the operations and arguments are valid Assembly instructions: you just need to separate them into tokens.

In this problem, you must implement a tokenizer for the Assembly instruction format: an operation type (e.g. SUBI) followed by a comma-separated list of parameters (e.g. R0, R1, 6). If a line has an invalid syntax, it should be skipped in the output.

Follow-up Question

I have something similar but I having difficulty for it passing the final test case

Sample Input 3

this file, tests
TEST a, b c
erroneous cases
TEST, a, b
there should, only, be
TEST, a b
six lines, in, the, output
TEST a band it, should
TEST a , b, c
include this, one
TEST a, b,, c

Sample Output 3

this file tests
erroneous cases
there should only be six lines in the output
and it should
include this one

Explanation 3

All of the lines beginning with TEST have some sort of syntax error, so they should be omitted from the output. The other lines have no errors, so they should be tokenized and output. The errors are as follows:

  • TEST a, b c: the comma between b and c is missing
  • TEST, a, b: there is an extra comma after TEST
  • TEST, a b: the comma between a and b is missing, and there is an extra comma after TEST
  • TEST a b: the comma between a and b is missing
  • TEST a , b, c: there is a space before the comma between a and b
  • TEST a, b,, c: there is an extra comma between b and c

My current output as of right now

this file tests

TEST a b c

erroneous cases

TEST a b

there should only be

TEST a b

six lines in the output

TEST a b

and it should

TEST a b c

include this one

TEST a b c
